Type:	Resources

Initialize scheduling algorithm

Parameters:	resources (Resources, optional) – available resources

Parameters:	min_cores (int) – minimum requested number of cores max_cores (int) – maximum requested number of cores
Returns:	created allocation None: not enough free resources
Return type:	Allocation
Raises:	`NotSufficientResources` – when there are not enough resources avaiable `InvalidResourceSpec` – when the min_cores < 0 or min_cores > max_cores

allocate_job(reqs)¶

Create allocation for job with given resource requirements.

Parameters:	reqs (JobResources) – job’s resource requirements
Returns:	created allocation or None if not enough free resources
Return type:	Allocation
Raises:	`NotSufficientResources` – when there are not enough resources avaiable `InvalidResourceSpec` – when resource requirements are not valid
